In everything one should see with one’s own eyes and know through one’s own knowledge

O Son of Spirit! The best beloved of all things in My sight is Justice; turn not away therefrom if thou desirest Me, and neglect it not that I may confide in thee. By its aid thou shalt see with thine own eyes and not through the eyes of others, and shalt know of thine own knowledge and not through the knowledge of thy neighbour. Ponder this in thy heart; how it behoveth thee to be. Verily justice is My gift to thee and the sign of My loving-kindness. Set it then before thine eyes. (Baha'u'llah, The Hidden Words)
